An Exceptional Antique Australian Opal Necklace, Vintage 14K White, Yellow, Pink, and Green Gold Filigree, Victorian - Art Deco Period, circa 1910-1920's. This is one of the most beautiful necklaces that I have come across in a long while. The center drop holds a genuine Australian Opal gemstone measuring about 10 x 14mm. It displays beautiful natural colors in the light. The opals is set in 14K yellow gold and is backed by black onyx as you can see on the reverse. The opal is suspended on a 14K white gold filigree chain with a rose gold flower with green gold leaves. The necklace closes with original 14K white gold floral clasp. The pendant portion measures about 1 3/8 inches long by about 1/2 inch wide. The entire necklace is about 16 inches long. This necklace dates to the late Victorian to Art Deco Era and is in lovely vintage condition. This pieces was acquired through a local estate collection and is a rare find.
